The invention relates to the technical field of computer vision, in particular to a system for modeling a 3D scene from a single design picture. The method comprises the following steps: rendering: randomly arranging objects in a rendering engine to obtain a rendering result graph and a data set of a 3D object transformation matrix of each object; model extraction: extracting a prediction model from the data set by using a deep learning network; instance segmentation: inputting a single scene design picture, and predicting an instance segmentation result and a transformation matrix of a 3D object of each instance; and modeling: placing an object corresponding to a single instance in a scene under the guidance of the transformation matrix to complete result modeling. According to the method, instance segmentation is performed by using the deep neural network MaskR-CNN to obtain the images of a 2D object bounding box and a bounding box area, and the 3D scene arrangement is automatically completed by a single design picture according to the 2D plane mapping of the 3D object corresponding to the instance segmentation result, so that the scene construction time can be greatly shortened, and the scene construction speed is increased.
